` 2 Claims.

This invention relates to nlm hangers especially designed for use inhanging X-ray nlms, the primary object of the invention being tolprovide a hanger which will ,be capable of adjustment for use inhanging nlms of various sizes.

Another important object of the invention is to provide an adjustablehanger wherein the hanger maybe readily and easily adjusted without theuse of tools.

Still another object of the invention is to provide a hanger which willhold the nlm nung therein, in stretched condition, so that the nlm maybe dried and accurately examined.

With the foregoing and other objects in View which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts, hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is an elevational View of an adjustable nlm hanger, constructedin accordance with the invention.

Fig. 2 is a sectional view taken on line 2 2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is an enlarged sectional View taken approximately on line 4-4 ofFig. 1.

Fig. 5 is a fragmental perspective view illustrating the end members ofthe device constructed of tubular material.

Referring to the drawing in detail, the hanger comprises an uppersupporting bar 5 which is of channel bar construction with its open sidedisposed downwardly, the longitudinal edges of the open side of the barbeing turned inwardly providing spaced flanges 6. The upper wall of thesupporting bar at each end thereof, is turned downwardly providing stops'I at the ends thereof.

The reference character 8 indicates a hanger rod which is connected withthe upper supporting ,bar 5 by means of the spaced vertical bars 9, thehanger rod 8 being designed to nt within suitable brackets (not shown)for hanging a nlm for examination and drying purposes. The referencecharacter I0 indicates the lower bar of the hanger which is alsoconstructed of channel bar material with its open side disposedupwardly, the longitudinal edges of the open side being eX- tendedinwardly providing nanges II. Portions of the lower bar are extendedupwardly at the ends thereof providing stops I2.

The side bars of the hanger are indicated generally by the referencecharacter I3, which side bars comprise telescoping upper and lowersections I4 and I5, respectively, the section I5 being movable withinthe open end of the section I4 so that the length of the hanger may b eadjusted by moving the sections I5 at the sides of the hanger Within thesections I4.

Enlargements I6 are formed on the inner surfaces of the section I4,which enlargements are adapted to move into openings formed in the sidesof the section I5, frictionally holding the sections I4 and I5 of theside bars, in their positions of adjustment.

At the upper ends of the section I4 are T-shaped plates I 1 that extendlaterally from the upper sections, the T-shaped plate being ntted withinthe open side of the upper supporting bar 5.

As shown, the bar 5 is formed with inwardly disposed enlargements I8that are adapted to nt into the depressions I 9 of the T-shaped platesI1, thereby holding the T-shaped plates I1 in their positions ofadjustment along the bar 5. The stops 'I at the ends of the bar 5 act torestrict outward movement of the T-shaped plates from becomingdisconnected from the upper supporting bar 5.

At the lower ends of the sections I5, are inwardly disposed plates 2ethat are of T-shaped construction to nt within the lower bar I0, the barI i) being provided with enlargements that nt into depressions formed inthe plates 2B to hold the plates in their positions of adjustment. Thestops I2 of the bar Ill act as means to prevent the lower ends of theside bars from becoming disconnected from the lower bar lli.

Openings are formed in the plates I'I and 2U, which openings accommodatethe hooks formed at the ends of the spring arms 2l of the nlm engagingclamps 22 that are shown as pivotally connected with the spring arms ZI.

These clamps 22 are designed to clamp the edges of the nlm hung on thedevice, the nlm in the present showing being indicated by the referencecharacter A.

From the foregoing it will be seen that due to the construction shownand described, I have provided a nlm hanger which may be adjustedlongitudinally and transversely so that it will properly support nlms ofvarious sizes.

In the form of the invention as shown by Fig. 5 of the drawing, thereference character 25 indi- Cates a portion of an upper or lower bar ofa hanger wherein the upper and lower bars are constructed of tubularmaterial, the tubular material having an open side to permit the plate26 secured thereto and which connects with the adjacent bar of thehanger, to extend therethrough, the plate 2E being connected to theinner tubular section 21 of the supporting bar for movement therein.

Havingv thus described the claimed is:

1. In a lm hanger, an upper supporting bar of channel constructionhaving its open side disposed downwardly, a lower bar of channelconstruction having its open side disposed upwardly, spaced parallelflanges extending inwardly from the open sides of said upper and lowerchannel bars, providing guideways, connecting bars connecting the upperand lower bars, T-shaped plates at the ends of the connecting barsfitted within the open sides of the upper and lower supporting barsadjustably connecting the side bars to the upper and lower supportingbars, means for holding the connecting bars in various positions ofadjustment with respect to the supporting bars, and clamps forming apart of the hanger clamping a lm securing the film to the hanger.

2. In a lm hanger, an upper supporting bar of channel constructionhaving its open side disposed inwardly, a lower bar of channelconstrucinvention, what is 4 tion having its open side disposedupwardly, parallel anges extending inwardly from the open sides of saidupper and lower channel bars providing guideways, connecting bars, saidconnecting bars embodying telescoping sections, T-shaped plates at theends of said connecting bars moving Within the open sides of the upperand lower supporting bars, stops on the supporting bars engaged by saidT-shaped plates restricting lateral movement of the connecting bars withrespect to the supporting bars, means for securing the connecting barsin adjusted positions with respect to the supporting bars, and clampssecured to the T-shaped plates for clamping a film, securing the film tothe hanger.
